How to Spot Fake Gold? Density Gold Analysis Guide
Fake or under-karat gold creates financial and reputational risk for jewelers. Acid tests, XRF and visual checks are common. For fast, chemical-free bench screening, density-based gold analysis is often the practical first step. Here’s how to spot fake gold and what density testing can and cannot prove.
How density gold analysis works
By weighing a piece in air and in water, you calculate density and compare it with known karat densities. A 0.001 g gold analysis balance improves reliability on smaller items. The CTL600-K gold analysis balance offers 600 g capacity and 0.001 g readability for Archimedes density screening.
Limits you should know
Tungsten cores can mimic gold density. Density is a strong pre-screen, not always a final verdict. Combine it with stamps, experience and secondary tests when needed.
FAQ
Can density testing always detect fake gold?
It catches many under-karat and mixed-metal fakes, but tungsten-filled pieces may require additional methods.
Is CTL600-K suitable for jewelry shops?
Yes. It fits daily purity pre-assessment with density analysis at 600 g / 0.001 g.
